You never know what you might find in a second-hand store!

Earlier this year, five previously unknown 90c self-adhesive Kapa Haka stamps were discovered tucked inside a book. These stamps were never intended to be produced for sale and, until this discovery, their existence was completely unknown.

Now, one is heading to auction in our upcoming sale.

Back in 1952, when this note was issued, £50 was A LOT of money; adjusted for inflation, today it would be the same as $3,900!
Fast forward to 1967, when NZ changed to decimal currency, most examples were cashed in, making this note scarce and sought after by collectors.

In 1840, the world’s first stamp was issued: the famous Penny Black! It was only issued for one year before being replaced by the Penny Red due to the postmarks not showing well when cancelled.

Many collectors will have one in the collection at some point, but this person went a step further with over 200 examples!

In 1933, New Zealand began producing its own coins, and just two years later, in 1935, the country issued its first commemorative coin set that included the Waitangi Crown.

Only 1,128 Waitangi Crowns were produced: 364 in Proof sets, 104 Proofs issued individually, and a further 660 in Uncirculated condition.
The design carries an important piece of New Zealand’s history, depicting Chief Tāmati Wāka Nene shaking hands with Captain William Hobson during the signing of the Treaty of Waitangi.
